How we handle construction mastic in Tower Hill
Mastic is often where a new building first shows its quality to the client. A smeared bead round a window or a gap behind a worktop ends up on the snag list. We seal so the snag list stays short, area by area through the programme. We work on brick and block movement joints, floor and skirting junctions and window and door perimeters, and the usual reasons a site gets in touch are sanitary sealant damaged by following trades and different trades sealing to different standards. A specialist sealant contractor works differently from a general builder: on jobs in Tower Hill, preparation and product choice get the time they need.
Construction in and around smaller places such as Tower Hill is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Why deal with it now?
When a package runs over budget, downgrading the product is a common first thought. The saving is small next to the cost of callbacks and defects, especially externally. We price the specified product and will tell you plainly where an alternative would or wouldn’t work. Halls, stores and units around places like Tower Hill may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Mastic packages on Tower Hill sites
At about 33 miles from central London, Tower Hill is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme. There are a number of hotels within about 2 miles of Tower Hill. When hotels extend or refit, the work is normally squeezed between peak periods, mastic included.
When a school such as St John's Catholic Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. For contractors refurbishing units at places like Tanbridge Retail Park, 0.6 miles north-east of Tower Hill, the mastic covers cladding panels, roller-door and window perimeters.

What we’re called out for in Tower Hill
Wide, tapered or inconsistent gaps around frames are a common problem. Sealant has a range of joint widths it can cope with and gaps beyond it need packing or adjusting by the frame installer. We flag them early rather than filling them with sealant that won’t last.
Most enquiries start with something like this:
- New external sealant already peeling away
- Different trades sealing to different standards
- Failed sealant in an existing building being refurbished
- A long mastic snag list close to completion
Hotels like The King's Head Hotel (to the north-east of Tower Hill) rarely close for long, so refurbishment mastic is phased floor by floor.

What the job involves on each surface
Snagging before handover
Snagging is often the final mastic stage. We can work through the snag list area by area.
Fire-rated sealant where specified
Not every penetration suits a sealant. Collars, wraps, batts and boards are specified for other services so we will flag where the detail needs something different. Tell us what records you need and we will confirm with the quote.
FAQs: Tower Hill
Is Tanbridge Retail Park, near Tower Hill, within your area?
Yes. We cover Tower Hill and the area around it, including industrial estates, business parks and retail parks such as Tanbridge Retail Park. Send details of the unit and the work through our quote form for a quick quote.
Is Tower Hill too small for you to travel to?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
How soon can the area be used again?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
What accreditations do you hold?
We’re CHAS accredited and a Constructionline member, with CSCS-carded applicators. We are also fully insured, with five million pounds of public liability cover.
How long does a job like this take?
It depends on the scope, though a typical visit normally takes as long as the agreed sequence needs, which comes down to joint lengths, access and handover dates. For bigger or phased jobs, we will set out a timescale with the quote.
Can you seal external joints in wet or cold weather?
Conditions have to suit the product before external work starts. Sealing in poor conditions risks adhesion failure, so we wait rather than redo work.
What about RAMS and site documents?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.
